This composite image, taken by the Very Large Array and Hubble, shows the galaxy cluster MACS J0717.5+3745. Pullout shows the distant galaxy J0717+3745, far beyond the cluster, and likely the faintest radio-emitting object ever detected. The prominent red-orange objects are radio relics -- large structures possibly caused by shock waves -- inside MACS J0717.5+3745.
